Bosonic decays of charged Higgs bosons in a 2HDM type-I

Charm Decays as Evidence for Charged Higgs Bosons

It is suggested that the recent anomalous data on Cabibbo-suppressed charm decays can be interpreted as a manifestation of a charged Higgs boson. If this were true, it would be the first experimental detection of a Higgs contribution. At the least, it demonstrates that large, interesting Higgs (i.e., scalar) contributions are consistent with present experimental constraints. Predictions are giv...

τ − ν τ Decays and Implications for Charged Higgs Bosons

Decays of the Higgs Bosons

We review the decay modes of the Standard Model Higgs boson and those of the neutral and charged Higgs particles of the Minimal Supersymmetric extension of the Standard Model. Special emphasis will be put on higher–order effects. Talk given at the International Workshop on Quantum Effects in the MSSM Barcelona, Spain, September 9–13, 1997. Decays of the Higgs Bosons Abdelhak DJOUADI Laboratoire...

Tools for Charged Higgs Bosons

In order to identify the Higgs sector realized in nature, the predictions for Higgs boson masses, production cross sections and decay widths have to be compared with experimental results. We give a brief overview about computer codes for the evaluation of the properties of charged Higgs bosons, mostly focusing on the case of the Minimal Supersymmetric Standard Model (MSSM). We briefly review th...

Light Charged Higgs Bosons in Supersymmetric Models

We point out that present experimental limits from searches for neutral Higgs bosons at LEP already imply stringent lower bounds on the mass of the charged Higgs boson in the Minimal Supersymmetric Standard Model (MSSM); these bounds are especially severe for low values of tanβ (tanβ ≤ 3), where the Ht̄b coupling is large. However, these indirect constraints are much weaker in simple extensions ...
